Ciaran Finn-Lynch, the now 13-year-old boy from the UK who the world's first child to receive the stem cell trachea transplant, is breathing normally and no longer needs anti-rejection medication, researchers reported in a paper published Wednesday in the journal Lancet.
The organ itself is strong, has not shown signs of rejection, and has even grown 11 centimeters since it had been transplanted, according to the researchers.
Ciaran was born with a rare condition known as Long Segment Tracheal Stenosis, marked by a small windpipe that does not grow and can restrict breathing. He underwent the stem cell transplant in March 2010 after a standard trachea transplant did not work.
